The Sun is a star. Many things have been said about it.
"Let it be so. Thy truth then be thy dower. For by the sacred radiance of the sun, The mysteries of Hecate and the night, By all the operation of the orbs From whom we do exist and cease to be— Here I disclaim all my paternal care, Propinquity, and property of blood, And as a stranger to my heart and me Hold thee from this for ever."
William Shakespeare: King Lear Act 1, Scene 2
"To this end the golden sun rules an orbit measured out in certain divisions through the twelvefold star-girdle of the world. Five zones are placed in heaven; whereof one ever reddens in the blazing sun and ever is parched by his fire; and round it right and left sweep the utmost two, bleak, stiff in ice and dark with showers; two between these and the central zone are granted by grace of the gods to weary mortals, and through both a path is drawn where the slant procession of the signs may turn. The world, rising steeply towards Scythia and the Rhipean fortresses, sinks sloping to Libya and the south. This pole of ours is ever uplifted; but the other black Styx and the deep world of ghosts see underneath their feet. Here the enormous Serpent glides forth, wreathing his coils in fashion of a river around and between the two Bears, the Bears that dare not dip under the Ocean floor: there, one saith, either dead night is soundless, and the gloom thickens in night's perpetual pall, or dawn returns from us and leads back the day; and when dayspring touches us with his panting horses' breath, there crimson Hesperus kindles his lamp at evenfall. Hence can we foreknow the changeful sky's seasons, hence the day of harvest and the time of sowing, and when it befits to drive our oars through the treacherous sparkling sea, when to launch armed fleets, or in due season lay low the woodland pine."Virgil: Georgics, page 301
